Rocky bodies impact the inner planets

Reference no: EM13219182

1. When large, rocky bodies impact the inner planets, they leave craters on the surface. Craters are observed on the planets and their moons, but the number of craters differs drastically between objects.
a. What are some reasons that there are not very many craters on the Earth? Describe the cratering on the Moon—is there a uniform amount of craters all over the surface, or does the amount of cratering vary in different places?
b. What does the amount of craters tell us about the age of the surface of the Moon, for example? How does the age of the surface of the Moon compare to the age of the surface of the Earth?

2. As the Moon orbits the Earth, it rotates once on its axis in exactly the same amount of time it takes to complete one orbit. Because of this synchronization of its orbital period and its rotation period, the Moon always keeps the same face pointed towards the Earth.
a. Describe the process that caused the Moon's orbit and rotation to achieve its current synchronization.
b. How does the orbit of Mercury around the Sun compare to the orbit of the Moon around the Earth? Does Mercury always keep the same face pointed at the Sun? Why or why not?

3. Venus, Earth, and Mars all have gaseous atmospheres, but the properties of each are very different.

a. Describe two differences between the atmospheres of each planet. Are the atmospheres of these three planets the same as they were several billion years ago? Why or why not?
